来自印度尼西亚爪哇岛 Cikalong 的真品 Carcharocles megalodon 牙齿

牙齿有修补痕迹，并经过抛光。

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“大牙齿”，是一种已灭绝的鲭鲨，生活于约 2300 万至 360 万年前（Mya），从早中新世延续至上新世。过去，人们认为它属于鼠鲨科，是大白鲨（Carcharodon carcharias）的近亲。然而，现在它被归入已灭绝的耳齿鲨科；该科在早白垩世时与大白鲨分化。

巨齿鲨被认为是有史以来体型最大、力量最强的捕食者之一，但目前仅发现零碎遗骸，因此其外形和最大体型尚不确定。科学家们对它究竟更像体型粗壮的大白鲨、鲸鲨（Rhincodon typus）、姥鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）看法不一。最新且误差范围最小的估算认为，其最大体长可达 20.3 米（67 英尺），体重可达 103 公吨（114 美制短吨）。

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon), meaning "big tooth", is an extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Pliocene epochs. It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias). However, it is now classified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous.

While regarded as one of the largest and most powerful predators to have ever lived, the megalodon is only known from fragmentary remains, and its appearance and maximum size are uncertain. Scientists differ on whether it would have more closely resembled a stockier version of the great white shark, the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus) or the sand tiger shark (Carcharias taurus). The most recent estimate with the least error range suggests a maximum length estimate up to 20.3 meters (67 ft),  weighs up to 103 metric tons (114 short tons)
